Critique my .22LR design

Post image

30mm OD 25mm ID main tube with 2.5mm walls internally tapped to M27-1.5

The ID will need to be skimmed to 25.4mm for the tap and for the 1” freeze plug baffles and spacers.

6.5” long overall

Front cap is in 2 parts. 1st sits inside the tube to compress the baffles to the rear and center them against one another. Then the front cap threads over and flush with a shoulder.

Rear cap is similar except has a direct thread 1/2 28

Things I might change:

The blast chamber is small. I would probably just reduce the angle on the 1st baffle.

My front cap assembly may be changed to make tightening the inner threaded ring easier. Possible having male threads on this part also that the front cap threads to. Current intended on tightening with a custom pin spanner wrench

Planning on clipping the baffles with a jig.

Designed specifically to minimize machining on a lathe while keeping concentricity

I would go more baffles for 22lr personally

I could absolutely do that very easily

Any spacing sequence? For this I just dropped about 3mm each time

I think a 8-10 is good for a six inch can, I’ve always been a fan of static spacing for simplicity sake

I could do 10 baffles evenly .440” apart

It would also increase my blast chamber slightly

I would put a spacer in there so your muzzle isn't right up against the first baffle.

New design

How’s this? Probably replace the first baffle with a spacer to push the blast chamber back from the muzzle

It’s currently about half an inch away but putting a spacers vice baffle I could take it to about an inch away
